Problems solved by technology
However, since the light pipe is coaxial with the ventilation pipe, the direction of the ventilation pipe is limited by daylighting, and the air can only flow through the annular channel between the light pipe and the ventilation pipe. In this case, the photocatalyst layer can only be arranged On the outside of the diffuser cover, the effective photocatalytic air purification area is limited by the diffuser cover area, and the purification efficiency is low; in addition, due to the lack of control over the indoor air flow, the efficiency of air purification has nothing to do with the light intensity, resulting in a waste of resources

Embodiment Construction
[0059] image 3 A schematic diagram showing an embodiment of the light guide lighting and air purification device of the present invention. This light pipe lighting and air purification device comprises a light channel 2 and an air channel 5, light enters the room from the light channel, air enters the room from the air channel, and the air channel 5 includes a light-transmitting air channel segment 4, a light-transmitting A photochemical material is arranged in the air channel section 4 , the photochemical material can be a photocatalyst, for example, the light-transmitting air channel section spans the inside of the light channel, and other parts of the air channel can be arranged outside the light channel. When the air flows in from the air channel 5 and passes through the transparent air channel section, it is radiated by the light in the light channel, such as natural light 15, and the air reacts with the photochemical material arranged in the transparent air section, and...

The invention relates to a light guide lighting and air purification device, system and method. The light guide lighting includes a light channel and an air channel. In the light channel, the light in the light channel is used to perform light radiation on the light-transmitting air channel section inside the light channel. Photochemical materials are arranged in the light-transmitting air channel. When the air passes through the light-transmitting air channel section inside the light channel, it reacts with the photochemical material in the light-transmitting air channel section to purify the air, so that the present invention realizes efficient Light guide lighting and air purification.
Description
technical field [0001] The invention relates to a device for light guide lighting and air purification, and a system and method for light guide lighting and air purification using the device. Background technique [0002] Daylighting with hollow light guide lighting systems is a commonly used technique. Since sunlight combined with photocatalyst chemicals can purify the air, solar air purification technology based on photoconductive lighting systems has also emerged. At present, there are two ways of air purification technology using light. The first is that the light path and the air purification path use the same path, and the second is that the air purification occurs after the end of the light path. [0003] U.S. Patent 5988843 discloses a kind of air purification channel technology using light, and its schematic diagram is as follows figure 1 shown. In this patent, the system uses a passage 6 to connect the interior and exterior spaces, sending sunlight and air from ...
